Australian Opposition Leader Tony Abbott will be Australia's next prime minister if the result of the latest opinion poll is played out on election day, Labor Party said on Sunday.

A Galaxy poll found the two-party preferred vote for the coalition was 51.4 percent to Labor's 48.6 percent.

ABC election analyst Antony Green said serious errors had been committed by whoever calculated the poll's two-party preferred vote.

The government, however, was taking seriously the poll's finding.

"If today's polls are right then Abbott could end up prime minister," Prime Minister Julia Gillard told the Nine Network on Sunday.

Meanwhile, the opposition leader maintains the election will be very hard for the coalition to win.

Australia's federal election was set on Aug. 21.
